A local alternative to Smallpdf
Smallpdf built a clean interface and a broad set of tools, with a free tier designed to lead into a subscription. PdfCanvas takes the opposite route: no account, no plan, no upload.
Where Smallpdf is the better choice
- You need conversions, compression, e-signature workflows or team administration.
- You want a business account with audit trails and centralized billing.
- You prefer a managed service with support rather than self-hosting.

What changes without an upload
The document is opened with the File API, rendered with PDF.js and edited in memory. Export writes a new file directly in the browser. Nothing is sent, so there is no retention window and no third-party processor in the data flow.
The editor also works after the page has loaded even if the connection drops, which matters on a corporate network that blocks large uploads.
What you give up
No cloud storage integration, no e-signature audit trail, no OCR, no compression. PdfCanvas is a document editor, not a document platform. For teams that need a paper trail, Smallpdf's managed workflow is the more complete product.
Frequently asked questions
+Do I need an account?
No. There is no sign-up, no email and no session to create. Open the editor and load a file.
+Is there a daily limit?
No. There is no task counter and no paywall. The only limit is the 200 MB default file size and your machine's memory.
+Does the free version add a watermark?
No. Exported PDFs are clean, because there is no upgrade to sell.
+Can I use it commercially?
Yes. The MIT license covers commercial use, including embedding the editor in a paid product.
